What??? bubbles??? I don't see how that would help much. This happened to my grandmother in the 70's. She got involved in a meditation group where you meet a spiritual guide. Only this guide was not a person from the other side or another plane of being. It turned out to be a demonic entity that tried to posess and attack her. Your aunt is in s-e-r-i-o-u-s danger. You need to tell her to immediately stop her meditations, hopefully this will end the posession as it did in my grandmother. If this has been going on for a while it may be too late to simply walk away from it. She has most likely (possibly unknowingly) invited the entity to come into her body. If this is the case you are going to need more than a positive bubble - you're going to need a preist. Good luck, my prayers are with you and your aunt.
